To all, w/wm u; may concern.-

Be it known that I, LUCIAN F. PLYMPTON, a citizen of the United States,residing at North Bend, in the county of Hamilton and State of Ohio,have invented a new and useful Improvement in Roofing-Tiles, of whichthe following is a specification.

My invention relates to such roofing-tiles as are shaped byforcing themoist element of which they are composed through a die and cutting offat the desired lengths, necessitating afterward the repressing of eachtile, so that when burned and placed upon the roof they may fit at thelaps.

It is by the above-described process that heretofore tile has been madeto [it at the partswhere one tile has to be placed upon an- I other uponthe roofviz., by repressing one an isometric projection oi upper tile;Fig. '5

end of each tile after it has once been forced through the die-therebymaking one end of the tile smaller than the die left it, orcausing it totaper in width, in order that it may lit into the other end of the tileas leftby the die. My invention corrects this defect, i having devised anovel-shaped lower tile having a rounded top, with parallel sidesthinner than the top and thickened at the bottom and edges and roundedat the edges, thesidosinelining outward.

A distinguishing feature of this tile is the thickened and roundededges, which renders it possible to shape them by forcingthe moistelement of which they are composed through a die, for should they beleft thin atthc edges theinc'reased friction-surface in proportion tothe surface pressure causes the edges to be torn'and haggled by theprocess of forcing the element through the die. I attain these objectsby the mechanism illustrated in the accompanying drawings,in whichFigure 1 is a plan View of a portion of the roof; Fig. 2, a section online 2 J of Fig. 1; Fig. 8, a section line 3 3 of Fig. 1; Fig. 4, an endView of the lower tile for laying with mortar; Fig. 5, an end view ofiopof tile; Fig. (i, an isometricprojection of lower tile; Fig. 7,

1 an end view of the lower tile for laying without mortar; Fig. 9,2111inside end view of die for making lower tilc; Fig. 10, a side elevationof Fig. 9; Fig. ii, a section on line 1 1 of Fig. 0; Fig. 12, an endview of die for making upper tile; Fig. 13, aside elevation of a portionpi" cylinder of the machine. Similar letters refer to similar partsthrou ghout the several views,

The line b c and the line I It are parallel and show the normalproportionate thickness of the bottom of my lower tile formed to be laidwithout mortar, the sides projcclingand thinner than the bottom, the topprojecting horizontally, and the edges the same thickness as the bottom,but rounded. It will be observed'that the upper surface and the undersurface of this tile extend in the same direction, that the periphery ofthe upper surface and the under surface is the same, and that this tilepresents the same crosssection at any part in its length, and that it issusceptible of being constructed by being once forced through a die, butit being necessary in certain instances to provide for mortarspace, (seethe die A, Fig. 9, where two rectangular plates having slots G and boltsii are slid perpendicularly toward each other and made secure byscrewing the nuts I, so as to partially obstruct the passage of the claythrough the die, thus shapingthe tile shown A, Fig-i-it being the, lowertile to be laid with mortar and differing only from tlie'formcr in this,that the bottom is thinned to form space-i. e., a tile having a Ilatcentral web with parallel sides andthickened edges and provided withinclined sides thickened and rounded at their edges) and each of theabove-described tile formed by one die.

My upper tile 0, formed to cover the upward extending and projectingsides and edges ol two under lilo to shed water into their troughs, isformed by once forcing the moist element of which they are composedthrough the die C, which imparts to it the shape of the die-orifice,producing a novelshaped upper tile with rounded top thicker than thedownward projecting sides and thickened at the edges equal to thethickness at the top, the edges projecting horizontally.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. An under tile for roofing having a ilat bottom, and parallel sidesinclined outward and upward, and thinner than the bottom, but thickenedand rounded atlhcir edges, prcsentingthe same cross section at any partin its length and the under surface and upper l the joints of asubstantially inverted U shape surface of which extend in the samedirecin cross section, said covering tile having :1 tion, substantiallyas described, and for the rounded top, with parallel sides thinner thanuses and purposes set forth. the top and thickened at the bottom and 2.An under tile for roofing, having a flat edges, and rounded at, theedges substantially central web, with parallel sides and thickened asshown and for the uses and purposes deedges, and provided with inclinedsides thiclcscribed. ened and rounded at their edges, substantiallyLUCIAN F. PLYMPTON. as described and for the uses and purposes set.forth.
